I wouldn't say DEI generally means
We need more people of group X regardless of all other factors
That sounds more like quotas or affirmative action taken to the literal extreme, since those programs typically include other factors as well.
DEI is more about respecting the value that diversity brings to a team and making sure you have an environment that allows for all sorts of people to be included and welcome.
That said, totally agree that Melania Trump and Usha Vance aren't "DEI wives." It is certainly hypocritical that they embody immigration stories and Melania in particular may be illegal. But I don't think anyone in the current regime is concerned one bit about consistency in ideology, it's really just whatever they can get away with that leads to more power.
Sneaky carbon tax lol
